Which SEO Agencies Offer Top AI SEO Services?

Which SEO agencies offer top AI SEO services? The names that keep coming up in 2026 are iPullRank, Seer Interactive, KodRank, Omniscient Digital, Siege Media, WebFX, Intero Digital, and The SEO Works. Each one sells a defined service for getting brands cited in ChatGPT, Perplexity, Gemini, and Google AI Overviews, not just ranked on Google. The right pick depends on your size, your industry, and whether your gap is strategy, content, or authority.

There's a catch worth knowing before you trust any "best AI SEO agencies" list, this one included. Nearly all of them are written by agencies, and nearly all of them put the author first. Searchbloom's 2026 ranking names Searchbloom the top pick. eSEOspace's list names eSEOspace. SeoProfy's GEO roundup puts SeoProfy at number one.

That doesn't make those lists worthless. It just means a #1 spot tells you who published the page, not who will do the best work for you. So this guide does two things: it profiles agencies that show up on rankings written by someone other than themselves, using each agency's own service pages, and it gives you a practical way to test any AI SEO agency before you sign, KodRank included.

What do AI SEO services actually include?

AI SEO services help your brand get found, understood, and cited inside AI-driven search: Google AI Overviews and AI Mode, ChatGPT, Perplexity, Gemini, and Copilot. The best agencies treat it as an extension of SEO rather than a replacement. Rankings still matter, because AI tools lean heavily on content that search engines already trust.

One thing to clear up first: "AI SEO" means two different things depending on who's selling it.

An agency that only means the first row is selling efficiency, not AI visibility. Ask which one they mean in the first call.

When the offer is genuinely about AI search, a solid engagement covers five layers:

1. AI visibility audit. The agency runs the questions your buyers actually ask through the major AI tools and records who gets named, who gets linked, and how you're described.
2. Answer-first content. Key pages get restructured so each section opens with a clear, quotable answer. Our guide on how to optimize content for AI search engines walks through this extraction-first approach.
3. Entity and technical groundwork. Schema markup, consistent brand details across the web, and confirmation that AI crawlers aren't blocked.
4. Off-site authority. Digital PR, reviews, and earned mentions on the publications models already rely on. Your own website alone rarely wins citations, which is why off-page work still matters.
5. Measurement. Citation share across a fixed set of prompts, AI referral traffic, and leads by source.

If an agency's proposal skips two or more of these layers, it's a partial service with a bigger label.

Top SEO agencies offering AI SEO services in 2026

These nine agencies appear on AI SEO and GEO rankings published by other companies, and each runs a defined AI search service on its own site. They're listed by fit, not ranked, because the "best" agency for an enterprise retailer is the wrong one for a 20-person SaaS startup.

iPullRank: best for enterprise brands that want depth

New York-based iPullRank is led by Mike King, who created the Relevance Engineering framework the agency now sells in place of traditional SEO. It builds its own tools, including Qforia for simulating query fan-out, and publishes The AI Search Manual for free. Reviewers note it isn't priced for everyone, so it suits large brands with real budgets and technical teams.

Seer Interactive: best for teams that want proof before promises

Philadelphia-based Seer has a dedicated GEO service and says it has worked on AI search since January 2023. Its stance is refreshingly cautious: there is no silver bullet, so test everything. It also runs paid media and analytics, which helps if you want AI search tied into a wider data picture.

Omniscient Digital: best for B2B SaaS content programs

Omniscient Digital is an organic growth agency for B2B software companies, with GEO, digital PR, technical SEO, and content production under one roof. It's a strong fit if your AI visibility problem is really a content-quality problem. Smaller B2C brands are outside its focus.

Siege Media: best for content-led brands that need earned media

Siege Media pairs GEO services with digital PR and content marketing. Its published case studies cover AI visibility work for brands like Zapier and Zendesk. That off-site muscle matters, because AI tools lean heavily on third-party mentions.

WebFX: best for teams that want dashboards and scale

WebFX built OmniSEO®, a platform that tracks where a brand appears across AI Overviews, ChatGPT, Perplexity, and Gemini. It's one of the few agencies publishing a price: enterprise GEO starts at $22,500 per month. The trade-off with any large agency is less senior attention per account, so ask who will actually do the work.

Intero Digital: best for brands that want a named framework

Intero Digital packages its AI search work as Intero GRO™, short for Generative Response Optimization. It targets ChatGPT, Copilot, Perplexity, and Gemini, and combines entity work, content, digital PR, and technical SEO. Ask to see how GRO differs in practice from a solid SEO-plus-GEO program.

First Page Sage: best for complex B2B and thought leadership

First Page Sage was founded in 2009 in San Francisco and combines SEO, GEO, and thought-leadership content. That suits technical B2B products where buyers need expert explanations. Some reviewers flag long strategy phases, so it fits patient teams better than ones needing quick wins.

RevenueZen: best for B2B SaaS teams measured on pipeline

RevenueZen positions GEO as a build on top of SEO, with interview-led content and reporting tied to organic pipeline. After merging with Eastern Standard, it can also cover website strategy. It's a good match for startups that need AI visibility to show up in the CRM, not just a report.

The SEO Works: best for UK and international brands

The SEO Works is an employee-owned agency with offices in Sheffield, London, and Leeds and more than 80 specialists. It runs AI SEO and GEO through a method it calls Universal Information Infrastructure. It reports growing DHL's AI citations by 287%, a figure worth asking about in detail during a pitch.

Where KodRank fits

Full disclosure: KodRank publishes this guide, so judge us by the same test as everyone else. We're a small, senior team that has delivered 150+ SEO projects, and you work directly with the specialists rather than an account manager. Our GEO services start with a free AI visibility audit and include entity mapping, content restructuring, schema, digital PR, and monthly AI visibility reporting.

We fit best when the website itself is part of the problem. Because we build and optimize under one team, slow templates, blocked crawlers, and messy structure get fixed in the same engagement. That's useful for Shopify stores, SaaS companies, and B2B firms that don't need an enterprise retainer.

How to choose an AI SEO agency

The best way to choose an AI SEO agency is to make it show you, not tell you. Any agency can add "GEO" to a services page in an afternoon. Far fewer can run a live test, explain what they found, and tell you what they won't automate.

Use this checklist on every shortlisted agency:

• Ask for a live prompt test. Give them 10 questions your buyers really ask. A capable agency will show where you appear in ChatGPT, Perplexity, Gemini, and AI Overviews, and who appears instead.
• Ask what "AI SEO" means to them. If the answer is mostly about AI-written content or faster audits, they're selling tools, not AI visibility.
• Ask how they measure progress. Look for a fixed prompt set, repeated runs, citation share, and AI referral traffic. AI answers change between runs, so a single screenshot proves nothing.
• Ask who handles off-site work. AI tools rely heavily on third-party mentions. An agency that only edits your pages can't move that layer.
• Ask who will do the work. The strategist in the pitch isn't always the person on your account.
• Ask for a case study with a method. You want the baseline, the prompts tracked, the timeframe, and what changed. A percentage with no method is marketing.

KodRank's guide on how to choose a good SEO company covers the general vetting process. The points above are the extra layer AI search adds.

Red flags to walk away from

Transparency is the thread running through all of this. If an agency is guarded about its process before you sign, it rarely opens up after.

What AI SEO services cost and how long they take

AI SEO pricing is rarely published, and results build over months rather than weeks. Here's what to realistically expect before you sign.

Cost. Most agencies quote only after an audit. WebFX is an exception, listing enterprise GEO from $22,500 per month, a tier aimed at large organizations. The scope drives the price more than the "AI" label, so compare proposals line by line: pages restructured, prompts tracked, earned mentions targeted, and technical fixes included.

Timeline. Restructured answers and schema fixes on pages that are already indexed can show movement within weeks. Wider citation share builds over three to six months, as digital PR and brand authority compound. Judge the trend over several weeks, because individual AI answers fluctuate.

Results. Expect three things to move: how often you're mentioned or cited across your prompt set, AI referral traffic in GA4, and leads by source. For most sites, AI referrals are still small next to organic search, so judge them on lead quality, not raw volume.

Do you need an agency, or can you do it in-house?

You can run AI SEO in-house if you have a strong writer, someone comfortable with technical SEO, and time to track prompts every month. The 90-day rollout in our AI SEO strategy framework is a good starting point.

An agency earns its fee when the gap is off-site authority, technical debt, or plain capacity. Those three are slow and expensive to build from scratch, and they're where most in-house AI SEO efforts stall.

Frequently asked questions

Which SEO agencies offer the best AI SEO services?

Agencies with well-documented AI SEO services in 2026 include iPullRank, Seer Interactive, Omniscient Digital, Siege Media, WebFX, Intero Digital, First Page Sage, RevenueZen, and The SEO Works. The best choice depends on fit: enterprise brands lean toward iPullRank or WebFX, B2B SaaS toward Omniscient Digital or RevenueZen.

What is an AI SEO agency?

An AI SEO agency helps your brand get mentioned, cited, and recommended in AI-driven search, such as ChatGPT, Perplexity, Gemini, and Google AI Overviews. It builds on traditional SEO with answer-first content, entity and schema work, digital PR, and tracking of how AI tools describe your brand.

What's the difference between AI SEO, GEO, and AEO?

GEO (generative engine optimization) aims to get your brand cited inside AI-generated answers. AEO (answer engine optimization) aims to make your content the direct answer to a question, in AI tools, featured snippets, or voice search. AI SEO is the umbrella term, though some agencies use it to mean using AI tools for SEO.

Can an agency guarantee my brand will appear in ChatGPT?

No. No agency controls what ChatGPT or any other AI tool says, and answers vary from one run to the next. A credible agency improves your odds through better content, technical access, and third-party authority, then measures how often you appear across a fixed set of prompts.

How much do AI SEO services cost?

Most AI SEO agencies quote after an audit rather than publishing prices. WebFX lists enterprise GEO from $22,500 per month, while smaller specialist teams typically scope work around your site and goals. Compare proposals on deliverables, such as prompts tracked and mentions earned, not on the "AI" label.

How long does AI SEO take to show results?

Fixes to pages that are already indexed, like answer-first rewrites and schema, can show movement within weeks. Broader citation share across AI tools usually builds over three to six months, as digital PR and brand authority compound. Track the trend over several weeks rather than single answers.

Do I still need traditional SEO if I invest in AI SEO?

Yes. AI tools draw heavily on pages that search engines already trust, so technical health, quality content, and backlinks remain the foundation. Treat AI SEO as an extra layer on top of solid technical SEO and on-page work, not a replacement for them.

How can I check if my brand appears in AI answers?

Write down 10 to 20 questions your buyers would ask, then run them in ChatGPT, Perplexity, Gemini, and Google. Note who is named, who is linked, and how you're described. Repeat monthly, or ask an agency for an AI visibility audit to get a structured baseline.

Can small businesses afford AI SEO services?

Yes, if the scope is focused. Smaller brands often compete well in AI answers because those answers name only a handful of businesses, and a clear niche expert can beat a bigger generalist. A focused program on your core questions and pages costs far less than an enterprise retainer.
